Gray said: "I did not refuse to play, but given Burnley had indicated they were 99 per cent sure of concluding club-to-club matters, I felt it prudent for all parties to discuss the possibility of non selection in the best interests of everyone involved.
Despite having an obvious interest in what clubs might have to say in the transfer window, it was Burnley who gave Charlton a price which was ultimately paid, followed by Burnley advising me they had accepted a bid and given me permission to talk.
Given everything moved so quickly last weekend, I didn't get the chance to thank the fans, club and staff for contributing to what was an enjoyable stay."
